1967 Caliper Rebuilding O-Rings vs lipseals

[Gary F.]

I am getting my front J56 calipers sleeved with stainless steel bores.  Are O-rings better than the lipseals?  I plan to drive it 3 to 4 thousand miles a year.

Oh, much much better. o-ring em and forget em. With lip seals that darned leak on the floor is always in your future. With 3-4,000 miles a year it might take a little time, but it will come.

I agree with Don. O-ring is the way to go. With lip seals, you need to apply brake pressure at least once a month or they WILL start leaking. Also, O-rings are not affected by rotor run-out like the lip seals.

I put new seals in mine 2 times. When the O-rings came out, I put them in (along with DOT 5) and never had a problem since.

There is a great article in the Volume 39, Number 1 Summer 2012 issue of "The Corvette Restorer" magazine that you will find informative/interesting. It is about seals vs "O" rings for the calipers.
